Abstract

Within the last couple of decades, the groundwater development in Egypt has become more and<br>more important. New communities and land reclamation projects have been recently established in the<br>area to the east of the Nile Delta to overcome the growing population problem in Egypt. Groundwater is<br>the second source of water in Egypt.<br>The present paper deals with the hydrogeological investigation using geoelectrical vertical<br>electrical sounding technique around the new communities, East Nile Delta. A number of 53 vertical<br>electrical soundings using Schlumberger electrode configuration with maximum current electrode<br>spacing “AB” = 1400m have been carried out by the authors. Raw data of 92 VES from (Ezz El Din,<br>1993 and Abd El-Gawad, 1997) are reinterpreted. Records of the water wells drilled in the study area<br>and chemical analysis for the water samples are been guided.<br>The interpreted VES data in the form of layer thickness and resistivities presented on the crosssections<br>are found not to be easily a sequence of continuous sedimentary lithologic layers due to of the<br>lateral changes in layer resistivities. Therefore, the geoelectrical resistivity layers lumped into three<br>Litho- resistivity zones with different hydrogeological conditions. Litho-resistivity zone (A) represents<br>the detrital surface cover. Litho-resistivity zone (B) represents the dry zone. Litho-resistivity zone (C)<br>represents the saturation zone in the study area.<br>Geoelectric cross-sections have been constructed. The different aquifers have been recognized<br>with main structural elements controlling these aquifers.
